FIELD: physics, optics.
SUBSTANCE: contact lens comprises an optical zone, a peripheral zone surrounding the optical zone, a front surface and a back surface having movement elements thereon. The movement elements are dimples. The dimples are spaced apart such that their centres are 300-400 mcm apart. The dimples have a depth between 20 mcm and 30 mcm and a diameter between 100 mcm and 300 mcm.
EFFECT: improved lens movement.
